Improving the Quality of Host Country Ethical Oversight of International Research: The Use of a Collaborative 'Pre-Review' Mechanism for a Study of Fexinidazole for Human African Trypanosomiasis.

Developing countries face numerous barriers to conducting effective and efficient ethics reviews of international collaborative research.

Moreover, poorly functioning review systems can impose substantial delays on the commencement of research, which needlessly undermine the development of new interventions for urgent medical needs.
